POLICE Scotland has reportedly launched an investigation into whether former Rangers owner Craig Whyte still has a role at the club.

Officers from the Economic Crime Unit are believed to have attempted to enlist the help of former chief executive Charles Green in their inquiries.

They are understood to have written to Mr Green, who stood down from his post in April this year and now lives in France, to ask for his assistance.

Police Scotland would not comment on the reports.

However, Jack Irvine, executive chairman of PR firm Media House, said on behalf of the club: "We are fed up hearing these stories. Craig Whyte is not involved in Rangers Football Club."

Mr Green stood down from his position in April this year following allegations he colluded with Mr Whyte to buy Rangers' assets after a period of administration.

The Ibrox club has asked law firm Pinsent Masons to investigate those claims, and though they found no evidence, they have passed files to Police Scotland, which, in turn, has asked Mr Green for his version of events.

BBC Scotland reported a source close to Mr Green saying that he was co- operating with police, while a similarly placed source for Mr Whyte said police had not contacted the former owner on the matter.

Police Scotland's Economic Crime Unit also want to speak to Mr Green about a document submitted to Companies House. The document is at the heart of Mr Whyte's claim he and Mr Green were working together.

When the Scottish Football Association transferred the liquidated company's membership to a new company the key requirement was the total lack of involvement of Mr Whyte.

Rangers also denied reports that two shareholder organisations - Blue Pitch Holdings and Margarita Holdings - who hold a 12% stake in the club - could be banned from voting at the club's annual general meeting this year.

Concerns had been raised that Blue Pitch Holdings and Margarita Holdings could be a front for either Mr Green or Mr Whyte.
